Abstract

Stock trading is a popular financial instrument worldwide. In Indonesia, the stock market is known as the Indonesia Stock Exchange (BEI), and one actively traded stock is PT Bank Central Asia (BBCA). However, predicting stock price movements is challenging due to various influencing factors. Investors use fundamental and technical analyses for decision-making, but results often vary. Machine learning, particularly random forest regression and linear regression algorithms, can be used for stock price forecasting. In this paper, we compares these two machine learning methods to forecast BBCA stock prices, aiming to provide more accurate and effective solutions for investor's investment and trading decisions. The evaluation results of cross-validation mean squared error (MSE), root mean squared error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE) for linear regression were 0.12848, 0.35807, 0.29570, and 0.0036%, respectively, while for random forest regression were 27473.76, 158.04, 142.70, and 1.7153%. These findings indicate that linear regression outperforms in forecasting performance.

Abstract

Comprehensive effectiveness analysis of water treatment plant maintenance systems To date, the Integrated Environmental Performance Measuring System (IEPMS) and the Overall Maintenance Performance Measuring Process (OMMP) have become the standards used in evaluating environmental performance, so good integration between these two systems is very important. The purpose of this study is how PT. B, B, C assesses the effectiveness of its maintenance, then how to evaluate the environmental performance of produced water and wastewater. As well as determining the performance indicators of the maintenance of the treatment plant and wastewater of PT. The following research uses descriptive. Based on the results of this study, it concludes that using the OMMP method, PT ABC Offshore has an overall maintenance performance of 5.388, which indicates a high level of maintenance performance. Next is equipment downtime, operating hours, and emergency working hours. Finally, the company's overall environmental performance scored 9.57 by entering the green zone and indicating that PT ABC Offshore met the environmental performance control target for 12 months. Root Cause Analysis (RCA) results show that only 1 KEPI is still in the caution zone and is recommended for improvement.

Abstract

Soil is an important element in a road construction, where the soil is a support for the structure above it. However, the conditions found in the field are found in many soils whose physical properties do not meet the standards for compressibility, permeability, and plasticity. The aim of the study was to determine the CBR value of clay soil after it was mixed with a mixture of red brick powder and Rengel lime powder. This research method is experimental research (true experiment). The results of this study obtained that soil with a mixture of 9% lime + 9% red brick produced a CBR value of 66.36% of the original soil CBR value of 17.22%. The CBR value achieves optimum stability in the soil composition with a mixture of 9% lime + 9% red brick resulting in a CBR value of 66.36%.

Abstract

Bagasse has not been utilized optimally because it has low nutrient content, it was necessary to add feed ingredients such as indigofera which has high nutrition and molasses was needed for further processing utilizing anaerobic fermentation or silage. This study aims to determine the nutritional quality of complete ration silage based on bagasse, indigofera and molasses with different compositions. Silage was carried out at the Laboratory of Nutrition and Feed Technology, Faculty of Agriculture and Animal Sciences, State Islamic University of Sultan Syarif Kasim Riau. The proximate test was carried out at the Laboratory of the Center for Biological Resources and Biotechnology Research, Agricultural University of Bogor. This study used a completely randomized design with a factorial pattern consisting of 2 factors, each treatment unit was repeated 3 times. Factor A was the level of bagasse + indigofera, namely A1 = 100% bagasse + 0% indigofera; A2 = 50% bagasse + 50% indigofera; A3 = 75% bagasse + 25% indigofera and factor B was the level of molasses, namely B0 = 5% molasses and B1 = 10% molasses. The variables measured were crude fat, ash content and BETN. The data obtained were analyzed based on analysis of variance by using Duncan's test at 5% and 1%. The results of this study indicated that there was an interaction between factor A and factor B (P<0.01) on crude fat content, ash content, and BETN. Factor A had a very significant effect (P<0.01) on the crude fat content, ash content, and BETN. Factor B had a very significant effect (P<0.01) on crude fat and BETN, but did not affect the ash content. It was concluded that treatment A2, namely the composition of bagasse 50% + 50% indigofera and treatment B0, namely molasses 5%, obtained the best results.

Abstract

Turbine Bearing is a piece of equipment used to keep the shaft rotating about its axis or to keep a linearly moving component on track. The operation at PLTA Maninjau also makes use of a Turbine Bearing with a Journal Bearing type. The turbine bearing of the Maninjau hydropower plant experienced an abnormality, with the bearing temperature rising from 60°C to 80°C. Using the fishbone diagram method and failure mode and effects analysis, the authors conducted a root cause analysis of the causes of the increase in turbine bearing temperature in this study (FMEA). The cause of the increase in. The cause of the increase in the temperature of the turbine bearing unit 2 of the Maninjau Hydropower Plant was found to be a misalignment caused by a small bearing clearance of 0.2 mm, which should have been 0.4 mm according to the design value, after conducting research using the observation method through data collection and data processing. And reduced cooling water effectiveness from 18.41% to 1.15%. As a result, corrective maintenance on Maninjau Hydropower Unit 2 is required.

Abstract

In a new Honda Jazz car, there is a rotten smell coming from inside the AC cabin, the temperature is not cold and causes the windshield to fog up. The purpose of the research is to find out the causes of damage to the AC system and appropriate maintenance actions. The method used is primary data, namely by direct inspection it is known that the refrigerant parameters are low on the pressure gauge manifold device on both sides LO 0.6–0.8 kg/cm2 and HI 8–9 kg/cm2. Damage to the capillary pipe is leaking. The action taken is to replace the capillary tube components, so the temperature parameters become LO=1.5–2.0 kg/cm² and HI=14.5–15 kg/cm². Once the pressure on the compressor, LO=4–6 kg/cm² and LO=7–10 kg/cm². The temperature is hot in the vehicle cabin. After replacing the compressor Normal pressure LO=1.5–2.0 kg/cm² and HI=14.5–15 kg/cm². Unstable Condenser temperature, LO=15Psi. HI=300–350Psi. cleaning is carried out at the temperature parameters LO=25Psi and HI=150 Psi, normal conditions. The hot room temperature = 29.2ºC and the cleaning action is carried out, then the temperature becomes = 16.8ºC, the AC room temperature returns to normal.
